Death

"Nobody missed me even when I was alive. Took them hours to find my body — I know, I was sitting there waiting for them. Olive Hornby came into the bathroom — 'Are you in here again, sulking Myrtle?', she said, 'because Professor Dippet asked me to look for you —' And then she saw my body... ooooh, she didn't forget that until her dying day, I made sure of that..."

On her final day of life, Myrtle was teased by student Olive Hornby. She had made fun of Myrtle's glasses and, as a result, left Myrtle sobbing. Myrtle then ran into one of the bathroom's stalls, took off her glasses and started crying. Shortly after Myrtle had entered the bathroom, Riddle entered and started speaking in Parseltongue in order to open the Chamber of Secrets, the entrance of which was hidden behind the bathroom sinks. The Monster of Slytherin (a basilisk) then emerged from the entrance to the Chamber of Secrets.

Myrtle, still in one of the stalls, recognised the voice as being from a boy. Opening the stall's door, she planned to yell at Riddle to go away. On Riddle's command, the Basilisk stared at Myrtle, and her eyes met with the monster's. Since looking at a Basilisk's eyes was a fatal act, Myrtle's body fell to the bathroom floor. Tom (Lord Voldemort) used her murder to make his first Horcrux: the Diary. Myrtle's body was later found by Hornby.

Post-mortem

1940s

Moaning Myrtle's bathroom

Following her death, Myrtle returned as a ghost so she could haunt student Olive Hornby in revenge for her teasing and insults. Olive went to the Ministry of Magic to restrain Myrtle, who was thereafter obliged to remain at Hogwarts School of Witchcraft and Wizardry. Myrtle haunted the bathroom where she had died, although she was sometimes seen in other bathrooms, and was even flushed into the lake occasionally. As a result of her haunting, her favourite lavatory was rarely used, and was thus available for clandestine activities, such as illegal potion-brewing, as long as one did not mind the company.

1992-1993 school year

The true importance of Myrtle's bathroom was that it contained an entrance to the Chamber of Secrets, the home of the basilisk of Salazar Slytherin. In the 1992–1993 school year, the Chamber was opened again, fifty years after its previous opening, by a Gryffindorfirst year, Ginny Weasley, who was possessed by the diary of the earlier opener, Tom Riddle. (The diary was a Horcrux, though it was described as a "memory" at the time.) Myrtle later flooded her bathroom in a fit of pique when Ginny tried to dispose of the diary by flushing it down one of Myrtle's toilets.

Harry and Ron later learned from Aragog the Acromantula that the murdered student had been killed in a bathroom, and Harry realised that the student must have been Myrtle. Myrtle was flattered by Harry's request that she tell the story of her death, the manner of which was one of the most important and interesting events of her short life. (It is possible that Harry was the first person to treat it as something worth asking about.) Myrtle remembered only having seen a pair of enormous eyes, but neither Harry nor Ron recognised this as a clue that the monster was a basilisk. Hermione had already deduced the monster's nature by library research before she was petrified, so Myrtle's clue was of no practical importance.

1994-1995 school year

"Oh, hello Harry, long time — no — see, hmm, I was circling a blocked drain the other day and I swear I saw some polyjuice potion. Not being a bad boy again, are you Harry? ...I'd put it in the water if I were you."

During the Triwizard Tournament Myrtle spent some time in the Prefects bathroom, spying on students bathing

During the 1994–1995 school year, Hogwarts School of Witchcraft and Wizardry hosted the Triwizard Tournament. Before the second task, the champions had to solve the mystery behind their golden eggs, which, when opened, emitted a harsh screeching sound. The secret was that the noise became speech when heard underwater. One champion, Cedric Diggory, decided to meditate upon the clue in the prefects' bathroom. Myrtle spied on Cedric in the tub, admitting to Harry that it took Cedric a long time to figure it out; nearly all the bubbles in the bath were gone by the time he cracked it. Cedric later suggested to Harry Potter that he take his egg the prefects' bathroom. With Myrtle's hints, Harry was able to decipher the riddle.[7]

Myrtle also appeared to Harry whilst he was in the Black Lake, and pointed him in the right direction to find the village of the merpeople, thereby helping him to reach the Tournament hostages before the other champions.

That same year, Myrtle briefly spotted some Polyjuice Potion in the drains and asked Harry if he had been doing any more illicit brewing, which he denied. Had Harry (or more likely, Hermione) investigated Myrtle's suspicions, it might have been discovered much earlier that Barty Crouch Jr. was impersonating Alastor Moody.

1996-1997 school year

"[…] he's sensitive, people bully him, too, and he feels lonely and hasn't got anybody to talk to, and he's not afraid to show his feelings and cry!"

Physical appearance

Myrtle was a squat student with dark lank hair with a fringe, pimples and thick glasses. She died in 1943 and became a ghost, wearing her school uniform, as well as her glasses, for eternity.

Personality and traits

Myrtle was constantly bullied during her education at Hogwarts, for both her physical appearance and her personality. Myrtle hardly ever smiled and took great offence at the smallest slight, crying rivers of tears and wailing. She was often upset so badly that she tried to kill herself, until she realised that she was already dead. Myrtle did tend to be happy when something bad happened to other students, like when Hermione Granger accidently gained cat fur, ears and a tail after taking a contaminated Polyjuice Potion.

She did, however, seem to warm to some male students, including Harry Potter and Draco Malfoy. Myrtle also appeared to be a desperate flirt; she constantly flirted with Harry Potter, and showed her desperation to find love by spying on students such as Cedric Diggory whilst he bathed in the prefects' bathroom. Myrtle liked to take bubble baths when she was alive, due to "all those pretty bubbles"[9].

Relationships

Harry Potter

During his education at Hogwarts School of Witchcraft and Wizardry, Harry was nice to Myrtle so she developed a crush on him. Harry wasn't exactly known to stay out of life-threatening trouble so Myrtle offered to share her toilet with him if the event of his death occurred. She also was more than happy to help Harry during his studies at Hogwarts, with any task; during his Second year she helped him solve the mystery of the Chamber of Secrets, by telling him how she died.

In his Fourth year she helped him solve the mystery of the Triwizard Tournament's second task. During his fourth year Myrtle acted — to an extent — sexually towards Harry, while he bathed in the Prefects' bathroom, causing him to feel uncomfortable as he did not reciprocate her feelings of attraction. She acts coldly to Harry when he has not visited her for a while, but still remains his friend.

Draco Malfoy

Myrtle also got on well with Draco Malfoy, who was Harry Potter's enemy whilst at Hogwarts. Despite Draco being prejudiced against Muggle-borns and constantly bullying and threatening Hermione Granger for being muggle-born, the two managed to become close as both needed company for comfort. Although it is possible that he is unaware of her status as a muggle-born.

They became friends whilst she comforted him during his Sixth year at Hogwarts; that year Draco had become a Death Eater and was feeling the strains of it as he was required to murder Albus Dumbledore. He shared his feelings and thoughts with Myrtle, who listened and comforted him. Also she seems to have taken preference of Draco to Harry as Harry never visits Myrtle when she asks him to.

Olive Hornby

Olive Hornby and Myrtle were very much enemies. Olive teased Myrtle about her glasses during school and constantly bullied her. When Myrtle was crying in the bathroom and then got killed by the basilisk, it was Olive who first saw her dead body. Myrtle wanted revenge on Olive so bad she stalked her where ever she went reminding her that it was her fault she was dead and how horrible she was. Myrtle even went so far to interrupt her brother's wedding, though that was enough for Olive, who went to the Ministry of Magic. The Ministry of Magic demanded Myrtle to stay at Hogwarts. Myrtle claimed she didn't forget her until her dying day.

Peeves

Both Peeves and Myrtle resided at the school and were known as bothersome. Myrtle did not like Peeves who took enjoyment in bothering her as he did to everyone. At "Nearly Headless" Nick's Death day party both Peeves and Myrtle attended, when Peeves heard Hermione Granger complaining about Myrtle he found it as the perfect time to cause trouble. Peeves called Myrtle over, Myrtle did not look happy to see him but Peeves informed her that Hermione was talking about her. Myrtle assuming she was talking behind her back ran off crying, Peeves seemed to enjoy her pain and began pelting her with peanuts. Myrtle later told Harry, Ron, and Hermione that Peeves made her so upset she wanted to kill herself but then of course she reminded herself that she's already dead.

Ronald Weasley and Myrtle seemed to not have a very good relationship. Ron was very blunt to her in which she would usually get upset and start to cry. An example of this is when she tells them that someone threw a diary at her in which he reminds her it can't hurt her and she yells at him. Ron seemed to think Myrtle was weird but was scared of her when she stood up to him and punched through his stomach and head to prove her point.

Ron also bugged her about keeping a secret for a person (Draco Malfoy) claiming where would she take it to the grave or the sewers. Ron also made a comment saying Tonks was starting to look like Myrtle since Sirius died. This was probably not a compliment to Tonks, as Myrtle always looked sad and angry.

Hermione Granger

It was shown that Myrtle did not like Hermione in the least. At Nearly Headless Nick's death day party, Hermione told Harry and Ron how horrible and whiny Myrtle was. Peeves who overheard this called Myrtle over. Peeves told Myrtle that Hermione was talking about her. Myrtle knew she must be talking about her meanly like most students did, Hermione however who never wanted to hurt Myrtle's feelings tried to tell Myrtle how she was only saying how pretty Myrtle was looking tonight. However Myrtle did not buy this and yelled at Hermione for lying to her and left the party crying.

To brew the Polyjuice potion Hermione was in Myrtle's bathroom quite a lot as she knew nobody would want to go there because of Myrtle's presence, Myrtle seemed cold to Hermione probably because of Hermione talking bad about her at the death day party. Myrtle did take great enjoyment in Hermione being upset though (also probably because of her talking behind her back at the party) when Hermione's potion turned her into a cat, Myrtle teased and laughed at Hermione only making Hermione feel worse about her cat like appearance. Harry had never seen Myrtle happier than when she was teasing Hermione.

Nearly Headless Nick

Myrtle's relationship with Nick is unknown, though he did invite her to his Death day party. Nick probably invited her because either he liked her, felt bad for her or because of the fact that she is also a ghost and dead. Nick and Myrtle seem not to have the same point of view on death. Nick, of course, celebrates it and Myrtle is highly offended and touchy about it, although she sometimes likes to talk about it at length.

Cedric Diggory

On the year of the Triwizard Tournament Diggory was greeted by Myrtle in the prefects bathroom on the 5th floor. When Harry took his golden egg into the bathroom to have a bath Myrtle talked about Diggory and said that he was "The Handsome One".

Moaning Myrtle was based on the concept of crying girls found in communal bathrooms, such as those in parties and discos.[11]

The myrtle tree is a close relative of the willow tree. "Moaning Myrtle" is a similar phrase to "weeping willow." Her name is also possibly related to the "Moaning Minnie," the British name for a German WWII artillery shell that made a distinctive moaning whine before it hit.

Though never seen or mentioned, Ron and Hermione may have seen Myrtle when they went back down the Chamber of Secrets to destroy Hufflepuff's Cup in Deathly Hallows.

The myrtle (Myrtus) is a flowering plant of southern Europe and north Africa. In Greek mythology, it was sacred to Aphrodite, goddess of love and beauty, and to Demeter, goddess of grain and fertility; Pausanias relates it to the tragedy of Adonis. The Roman poet Virgil relates the myrtle to Venus and used them in wedding rituals, something that Jewish liturgy, which deemed it sacred, also used. Myrtle has also uses in Wiccan rituals, and was considered medicinal by the ancients, including Hippocrates, Pliny, Galen and Arabian writers.[12]

Myrtle's surname was never mentioned in canon, however in 2015, after being asked by a fan over Twitter, JK Rowling announced it was Warren and that Myrtle also had a middle name (Elizabeth). Rowling also referred to the middle name of Elizabeth as "just one of those classic British middle names".

In one scene of Chamber of Secrets, Ron jokingly suggests that Tom Riddle earned his Special Award for Services to the School for killing Myrtle; this foreshadows the fact that Riddle did indeed kill her.

Myrtle is shown to have a crush on Harry throughout the series. In the Goblet of Fire film, the bathroom scene shows her acting sexually towards Harry.

Hermione and Myrtle have a lot in common. They are both Muggle-born and both Hermione and Myrtle run to the girls' lavatory upon being teased by classmates, a move that puts both in mortal danger (from a troll and basilisk, respectively). But while Hermione is saved by a repentant Ron and Harry, Myrtle is killed by the unfeeling Riddle.

Apparently she never informed anyone about her death until she told Harry, Ron and Lockhart. It's unknown why she never told Armando Dippet or Albus Dumbledore about the cause of her death. It is possible that shortly after her death she was too distraught or traumatised to talk about it and was not asked for fear of upsetting her.

↑Technically, graduate students such as Albus Dumbledore are still Hogwarts students, and played by actors older than Henderson. Myrtle, being dead and not actively studying, is neither an active student. Although she died in 1943 and must have been 60 to 68 years old when she first appeared in the novels, she stopped aging when she became a ghost, and thus she can arguably be considered a teenager.
